Tetraphis pellucida Pellucid Four-tooth Moss

An autoicous, acrocarpous moss which is often found on decaying logs and stumps but also on peaty banks in woodland and on acidic rocks covered with peaty soil. Non-fertile shoots often have gemma cups at their tips which often occur en masse in loose tufts and give this species a distinctive appearance. It is a calcifuge species which is very common in Britain, particularly in the west and north but it tends to be scarcer in the highly oceanic areas of western Britain. It is surprisingly scarce in Ireland but widespread and common in Wales. In West Glamorgan it is found commonly on logs in deciduous and coniferous woodlands. Sporophyte capsules are occasional and then abundant.
